Finding weekends boring and looking forward to Mondays

I was diagnosed with combined ADHD a few weeks ago and I’m currently still on titration, taking Concerta XL 54mg.

I really struggle with weekends. I only really meet up with around three close friends, and even that is irregular because they work different hours or have other commitments. When I do meet them, I really enjoy it because it feels like I’m “charging my social battery.” During the week, I barely speak to anyone outside my family, and my job is not very social or vocal.

Some weekends, I do not meet any friends at all, and I find that quite difficult. I usually try to go out on weekends, but I do not really enjoy doing solo activities. Does anyone else with ADHD find this to be the case?

I often find myself looking forward to Monday because weekdays feel more structured and productive. On Friday evenings, I can feel quite sad unless I already have plans for the weekend.

It is also harder because I cannot really drive, I get tired quickly, and I have Crohn’s disease. This limits the places I can go, especially if they are far away or difficult to access by public transport.

I struggle to make friends as if I find people boring or not a "good match", then this puts me off, and I would rather spend time by myself than with people who I don't enjoy the company off, if that makes sense?

How do other people manage weekends when they do not have social plans? I am thinking of maybe volunteering, studying for something, or trying to find a part-time job for the weekend that involves socialising with people, for example working in retail, but this is something to consider down the line.
